DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] The present utility model provides two technical solutions:

[0028] Figures 1 - 5 The first implementation manner is shown: a full-screen concentrating photovoltaic module, including a bracket 1, an installation frame 2 is fixedly installed on the outside of the bracket 1, a concentrating plate 4 is fixedly installed on the top of the installation frame 2, and a cleaning mechanism 3 is arranged at the bottom of the installation frame 2 for cleaning the concentrating plate 4. The cleaning mechanism 3 includes:

[0029] A filtering component 31, arranged at the bottom of the installation frame 2;

[0030] A liquid storage component 32, arranged below the installation frame 2. The liquid storage component 32 includes a liquid storage tank 321, and the inner cavity of the liquid storage tank 321 is separated into two parts by a partition 324;

[0031] The spraying assembly 33 is arranged at the rear side of the mounting frame 2. The spraying assembly 33 includes a suction pump 331 installed at the rear side near the top of the liquid storage tank 321. The water outlet of the suction pump 331 is fixedly communicated with a water outlet hose 338. The end of the water outlet hose 338 is fixedly communicated with a spray pipe 339. A plurality of nozzles 3310 are fixedly communicated with the outer wall of the spray pipe 339. The water inlet of the suction pump 331 is fixedly communicated with a water inlet pipe 332. A circular cover 333 is arranged on the outer surface of the water inlet pipe 332. A support plate 334 is fixedly installed on the inner wall of the circular cover 333. A flow disturbing vane 335 is rotatably arranged on the top of the support plate 334 through a rotating shaft. The suction pump 331 simultaneously extracts clear water and a cleaning agent. When the clear water and the cleaning agent flow through the circular cover 333, under the action of water pressure, the flow disturbing vane 335 rotates, thereby changing the flow state of the fluid and mixing the clear water and the cleaning agent together. A clear water filling port 322 is arranged at the position near the right side of the top of the liquid storage tank 321. A cleaning agent filling port 323 is arranged at the position near the left side of the top of the liquid storage tank 321. A heating pipe 325 is arranged on the inner wall of the liquid storage tank 321. By appropriately heating the clear water in the liquid storage tank 321 through the heating pipe 325, the problem that the mixing effect of the clear water and the cleaning agent is poor due to low temperature can be effectively avoided. The water inlet pipe 332 is arranged in the inner cavity of the liquid storage tank 321. A connecting pipe 336 is fixedly communicated with the outer wall of the water inlet pipe 332 at the position below the circular cover 333. The connecting pipe 336 penetrates through the outer wall of the partition plate 324 and extends to the other side. An electromagnetic valve 337 is arranged on the outer wall of the connecting pipe 336. The spray pipe 339 is fixedly installed on the rear surface of the mounting frame 2 through a pipe clamp 3311. The liquid in the liquid storage tank 321 is sprayed out from the nozzles 3310 through the water outlet hose 338 and the spray pipe 339 in sequence, and the dirt on the surface of the condenser plate 4 is washed.

[0032] Figures 1 - 5 The second embodiment is shown. The main difference from the first embodiment is that: symmetric sliding grooves 21 are formed at the position near the front side of the bottom of the mounting frame 2. The filtering assembly 31 includes a cylinder 311 fixedly installed at the position near the front side of the bottom of the mounting frame 2. The telescopic end of the cylinder 311 is fixedly installed with a filtering box 312. The inside of the filtering box 312 is in a cavity state. Symmetric sliders 314 matched with the sliding grooves 21 are fixedly installed on the top of the filtering box 312. A filtering hole 313 communicated with the inner cavity is formed on the top of the filtering box 312. A drain hose 315 communicated with the liquid storage tank 321 is arranged at the bottom of the filtering box 312.

[0033] Through the provided filter box 312, during rainy weather, rainwater can flow down along the inclined surface of the condenser plate 4 into the filter box 312 and enter the liquid storage tank 321 through the drainage hose 315, thereby effectively saving a certain amount of water resources and reducing the cleaning cost. The impurities in the rainwater can be filtered through the filter holes 313 provided on the filter box 312, thus improving the cleanliness of the rainwater. When the cylinder 311 contracts, the filter box 312 is moved backward so that the condenser plate 4 can completely cover the filter box 312, thereby avoiding the long-term exposure of the filter box 312 to the external environment and reducing the dust covering the surface of the filter box 312. At the same time, since the top surface of the filter box 312 contacts the bottom surface of the mounting frame 2, when the filter box 312 moves backward, the mounting frame 2 can also scrape off the sundries on the surface of the filter box 312, thereby reducing the frequency of later maintenance.

[0034] Meanwhile, the content not described in detail in this specification belongs to the well-known prior art in the art.

[0035] In use, an appropriate amount of clean water and detergent are added to the liquid storage tank 321 through the clean water filling port 322 and the detergent filling port 323 respectively. Then, the solenoid valve 337 is opened, and the clean water and detergent are simultaneously extracted by the suction pump 331. When the clean water and detergent flow through the circular cover 333, under the action of water pressure, the turbulence blades 335 rotate, thereby changing the flow state of the fluid, making the clean water and the cleaning agent mix together. And the mixed liquid sequentially passes through the outlet hose 338 and the spray pipe 339 and is sprayed out from the nozzle 3310 to wash the dirt on the surface of the condenser plate 4. And due to the surfactant contained in the mixed liquid, the adhesion of the dirt on the condenser plate 4 is reduced. After the adhesion of the dirt is reduced, the solenoid valve 337 is closed, and the clean water is used to wash all the remaining mixed liquid and dirt on the surface of the condenser plate 4, improving the cleanliness of the surface of the condenser plate 4. By adopting the spray cleaning method, the scratching damage to the surface of the condenser plate 4 is avoided, and the service life of the condenser plate 4 is improved. And when the temperature is relatively low, the clean water in the liquid storage tank 321 is appropriately heated by the heating pipe 325, which can effectively avoid the problem of poor mixing effect of the clean water and the cleaning agent caused by low temperature. Through the provided filter box 312, during rainy weather, rainwater can flow down along the inclined surface of the condenser plate 4 into the filter box 312 and enter the liquid storage tank 321 through the drainage hose 315, thereby effectively saving a certain amount of water resources and reducing the cleaning cost.
